Tires age silently. Even if they look fine, hidden wear could compromise safety. Here’s how to know when it’s time to replace them.
Tread Depth Below 2/32”
Use a tread depth gauge—or the classic coin test. If you can see the top of Lincoln’s head on a penny, your tires are too worn.
Cracks or Bulges
Visible cracks or bulges on the sidewall indicate internal damage. Replace immediately—these are warning signs of a possible blowout.
Uneven Wear
If one side wears faster than the other, it’s often due to poor alignment or suspension issues. Fix the cause, then replace the tire.
Vibrations While Driving
Unusual vibrations might mean your tires are unbalanced or damaged. Don’t ignore it—it’s your car talking to you.
Tires Older Than 5 Years
Even if rarely used, rubber degrades over time. Experts recommend replacement every 5–6 years.
